Question

我有一个查询

SELECT c
FROM c 
join locales in c.locales
WHERE locales.country = 'SE' AND
locales.language = 'sv' AND
locales.categories[0] = 'Dam'

我试图将其调整为仅显示WHERE子句中指定的相关语言环境，所以我尝试将其调整为：

SELECT c.locales[0]
FROM c 
join locales in c.locales
WHERE locales.country = 'SE' AND
locales.language = 'sv' AND
locales.categories[0] = 'Dam'

但是这没有帮助，因为它可能不是locales [0]，我曾假设联接将使数组的相关部分始终显示为索引[0]，但我错了

如何调整查询以显示整个文档，但仅显示语言环境数组中的相关部分？

请注意，我希望显示整个文档，但只显示该数组中的相关区域设置。

文档如下：

马特。根据您的描述，我认为您可以进行如下更改：

SELECT locales
FROM c 
join locales in c.locales
WHERE locales.country = 'SE' AND
locales.language = 'sv' AND
locales.categories[0] = 'Herr'

输出：

更新sql：

SELECT c.id,c.artno,c.XXX(what properties you want),.....
,locales
FROM c 
join locales in c.locales
WHERE locales.country = 'SE' AND
locales.language = 'sv' AND
locales.categories[0] = 'Herr'

我可以将查询调整为仅显示相关区域设置吗？
